From 3c85234b979af71cb9db5eb976ea08a468415767 Mon Sep 17 00:00:00 2001 From: Felix Gu Date: Sat, 31 Jan 2026 01:13:45 +0800 Subject: cache: starfive: fix device node leak in starlink_cache_init() of_find_matching_node() returns a device_node with refcount incremented. Use __free(device_node) attribute to automatically call of_node_put() when the variable goes out of scope, preventing the refcount leak.
